 Read Before Printing

 

Drying

Always dry the filament at 80-100°C for 4-6 hours before every print job.

Nozzle

A ≥ 0.4mm hardened steel or other wear-resistant nozzle (e.g., ruby, tungsten carbide) is mandatory

Hotend

An all-metal hotend capable of reaching and maintaining 320°C is required.

Enclosure

A passively heated or actively heated enclosed build chamber is recommended to maintain a stable ambient temperature, which prevents warping and improves layer adhesion.

Extruder

A direct drive extruder is the most recommended for precise control over filament flow and retraction.

Build Surface

A PEI sheet, Garolite (G-10), or glass bed with a PVP-based glue stick is recommended.

AMS

Not compatible

Best practices when printing

Print directly from a heated filament dryer or a dry box with active desiccant (<15% RH) to maintain a dry state throughout the printing process.

 Post-Processing

Support Removal
  • Wear safety glasses to protect your eyes from sharp fragments.
  • It's often easier to remove support structures while the part is still warm.
  • Use needle-nose pliers and flush cutters for precise removal.

Annealing

(Optional Heat Treatment)

Annealing can significantly increase the heat resistance (HDT), stiffness, and strength of your PPA-GF parts.

  1. Preparation: Clean the part and remove all support material.
  2. Placement: Place the part on a flat, oven-safe surface (like a metal or glass sheet) to prevent distortion. For complex parts, consider placing them in a bed of sand to support all features.
  3. Heating: Heat the part in a convection oven at 90°C for 4 hours.
  4. Cooling: Turn the oven off and allow the part to cool down slowly to room temperature inside the oven. Do not remove it early, as this can induce thermal shock and stress.
